Guideline for the Treatment of Breakthrough and the Prevention of Refractory Chemotherapy-Induced Nausea and Vomiting in Children With Cancer

Outcome of antiemetic prophylaxis among pediatric cancer patients receiving moderate to highly emetogenic chemotherapy at pediatric hemato-oncology ward of Tikur Anbessa specialized hospital: A prospective observational study

INTRODUCTION

Chemotherapy-induced nausea and vomiting (CINV) is a major issue for chemotherapy pediatric patients, especially in developing countries due to limited access to essential antiemetics. This study aimed to assess antiemetic prophylaxis outcomes in pediatric cancer patients at Tikur Anbessa Specialized Hospital in Addis Ababa, Ethiopia.

METHODS

A longitudinal prospective observational study design was conducted among 201 pediatric cancer patients followed up to 120 h post-chemotherapy.

RESULTS

The majority of patients (75.1%) received combination prophylactic antiemetics in the acute phase. Complete response (CR) was the highest in the acute phase (71.1%). Emesis episodes occurred most frequently on the first day of treatment (28.4%) and gradually decreased over time. History of motion sickness, platinum-based chemotherapy, and prior chemotherapy-induced vomiting (CIV) were associated with emesis during the acute phase whereas multiple-day chemotherapy, prior CIV, receipt of antiemetics, and a history of motion sickness in the delayed phase. However, the odds of CIV were reduced with steroid presence in the chemotherapy regimen.

CONCLUSIONS

A considerable number of participants could not achieve a CR. It is important for clinicians to be cognizant of risk factors that influence the outcome of antiemetic prophylaxis to achieve better control of CINV among pediatric cancer patients.

A Dutch paediatric palliative care guideline: a systematic review and evidence-based recommendations for symptom treatment

BACKGROUND

Children with life-threatening and life-limiting conditions can experience high levels of suffering due to multiple distressing symptoms that result in poor quality of life and increase risk of long-term distress in their family members. High quality symptom treatment is needed for all these children and their families, even more so at the end-of-life. In this paper, we provide evidence-based recommendations for symptom treatment in paediatric palliative patients to optimize care.

METHODS

A multidisciplinary panel of 56 experts in paediatric palliative care and nine (bereaved) parents was established to develop recommendations on symptom treatment in paediatric palliative care including anxiety and depression, delirium, dyspnoea, haematological symptoms, coughing, skin complaints, nausea and vomiting, neurological symptoms, pain, death rattle, fatigue, paediatric palliative sedation and forgoing hydration and nutrition. Recommendations were based on evidence from a systematic literature search, additional literature sources (such as guidelines), clinical expertise, and patient and family values. We used the GRADE methodology for appraisal of evidence. Parents were included in the guideline panel to ensure the representation of patient and family values.

RESULTS

We included a total of 18 studies that reported on the effects of specific (non) pharmacological interventions to treat symptoms in paediatric palliative care. A few of these interventions showed significant improvement in symptom relief. This evidence could only (partly) answer eight out of 27 clinical questions. We included 29 guidelines and two textbooks as additional literature to deal with lack of evidence. In total, we formulated 221 recommendations on symptom treatment in paediatric palliative care based on evidence, additional literature, clinical expertise, and patient and family values.

CONCLUSION

Even though available evidence on symptom-related paediatric palliative care interventions has increased, there still is a paucity of evidence in paediatric palliative care. We urge for international multidisciplinary multi-institutional collaboration to perform high-quality research and contribute to the optimization of symptom relief in palliative care for all children worldwide.

Palonosetron in pediatric patients: A single-center, retrospective evaluation of policy and clinical practice guideline discordance

INTRODUCTION

Clinical practice guidelines (CPGs) recommending palonosetron for the prevention and management of chemotherapy-induced nausea and vomiting (CINV) were adapted for use at our institution. Palonosetron was restricted for use in patients experiencing breakthrough CINV and receiving highly emetogenic chemotherapy (HEC) or undergoing stem cell transplant conditioning and in patients with refractory CINV receiving HEC. Given the significant cost of palonosetron, we aimed to determine the proportion of chemotherapy blocks where palonosetron use was discordant with the institutional policy or source CPG.

METHODS

A retrospective review of the health records of patients who received palonosetron between 1 July 2019 and 30 June 2020 was undertaken. Details of palonosetron use, antiemetic regimen and the date and time of each vomit during the acute and delayed phases were collected for each chemotherapy block where palonosetron was given. Discordance with the institutional policy and the source CPG was determined by assessing the indication for palonosetron and the dose. In the subset of chemotherapy blocks where information regarding vomiting episodes was available, the extent of acute phase chemotherapy-induced vomiting (CIV) control was reported.

RESULTS

Four hundred thirty-eight chemotherapy blocks, representing 122 patients (mean age 9 years), receiving 595 palonosetron doses were included. Palonosetron use was discordant with institutional policy during most (72%; 314/438) of the chemotherapy blocks analyzed. However, palonosetron use was concordant with the source CPG during most chemotherapy blocks (74%; 326/438). Complete CIV control during the acute phase was observed in 66% (195/295) of chemotherapy blocks where palonosetron was given, irrespective of concomitant antiemetics administered.

CONCLUSION

The majority of palonosetron use at our institution was discordant with institutional policy, but concordant with the source CPG. Our institutional policy has since been updated to be more aligned with the source CPG.

Palliative care for children: methodology for the development of a national clinical practice guideline

BACKGROUND

Provision of paediatric palliative care for children with life-threatening or life-limiting conditions and their families is often complex. Guidelines can support professionals to deliver high quality care. Stakeholders expressed the need to update the first Dutch paediatric palliative care guideline with new scientific literature and new topics. This paper provides an overview of the methodology that is used for the revision of the Dutch paediatric palliative care guideline and a brief presentation of the identified evidence.

METHODS

The revised paediatric palliative care guideline was developed with a multidisciplinary guideline panel of 72 experts in paediatric palliative care and nine (bereaved) parents of children with life-threatening or life-limiting conditions. The guideline covered multiple topics related to (refractory) symptom treatment, advance care planning and shared-decision making, organisation of care, psychosocial care, and loss and bereavement. We established six main working groups that formulated 38 clinical questions for which we identified evidence by updating two existing systematic literature searches. The GRADE (CERQual) methodology was used for appraisal of evidence. Furthermore, we searched for additional literature such as existing guidelines and textbooks to deal with lack of evidence.

RESULTS

The two systematic literature searches yielded a total of 29 RCTs or systematic reviews of RCTs on paediatric palliative care interventions and 22 qualitative studies on barriers and facilitators of advance care planning and shared decision-making. We identified evidence for 14 out of 38 clinical questions. Furthermore, we were able to select additional literature (29 guidelines, two textbooks, and 10 systematic reviews) to deal with lack of evidence.

CONCLUSIONS

The revised Dutch paediatric palliative care guideline addresses many topics. However, there is limited evidence to base recommendations upon. Our methodology will combine the existing evidence in scientific literature, additional literature, expert knowledge, and perspectives of patients and their families to provide recommendations.

Efficacy and Safety of Olanzapine for the Prevention of Chemotherapy-induced Nausea and Vomiting in Children: A Systematic Review and Meta-analysis of Randomized Controlled Trials

Chemotherapy-induced nausea and vomiting (CINV) remain the most distressing event in patients receiving highly emetogenic chemotherapy (HEC) and moderately emetogenic chemotherapy (MEC). This meta-analysis was conducted to evaluate the efficacy and safety of olanzapine containing regimen in preventing CINV in children on HEC and MEC. We searched PubMed, Embase, and Cochrane central register of controlled trials electronic databases to identify randomized clinical trials that compared 2 groups who either got olanzapine (olanzapine group) or placebo/no olanzapine (control group) for the prevention of CINV in children. The primary outcome was to determine the efficacy of olanzapine (complete response). The secondary outcomes were nausea control, the need for rescue medications, and adverse events of olanzapine. Three randomized clinical trials (n=394 patients) were included in this meta-analysis (olanzapine group, n=194, and placebo/control group, n=200). The pooled analysis of this meta-analysis found that olanzapine had a higher complete response in all phases of emesis in the HEC group and only in the acute phase in HEC/MEC groups compared with the control group. Olanzapine had higher nausea control in all phases of HEC but no nausea control in HEC/MEC. Olanzapine also reduced the need for rescue medications. A significant number of patients in the olanzapine group experienced somnolence (grades 1 and 2), but none of the participants discontinued the study due to side effects. In conclusion, this meta-analysis showed that olanzapine significantly prevented CINV in HEC. There was also a lesser need for rescue medications in the olanzapine group. Somnolence was higher in the olanzapine group, but it was clinically insignificant.

Children's Oncology Group's 2023 blueprint for research: Cancer control and supportive care

The objective of the Cancer Control and Supportive Care (CCL) Committee in the Children's Oncology Group (COG) is to reduce the overall morbidity and mortality of therapy-related toxicities in children, adolescents, and young adults with cancer. We have targeted five major domains that cause clinically important toxicity: (i) infections and inflammation; (ii) malnutrition and metabolic dysfunction; (iii) chemotherapy-induced nausea and vomiting; (iv) neuro- and oto-toxicty; and (v) patient-reported outcomes and health-related quality of life. Subcommittees for each domain prioritize randomized controlled trials and biology aims to determine which strategies best mitigate the toxicities. The findings of these trials are impactful, informing clinical practice guidelines (CPGs) and directly leading to changes in the standard of care for oncology practice. With the development of new therapies, there will be new toxicities, and the COG CCL Committee is dedicated to developing interventions to minimize acute and delayed toxicities, lessen morbidity and mortality, and improve quality of life in pediatric and young adult patients with cancer.

Chemo assist for children mobile health application to manage chemotherapy-related symptoms in acute leukemia in Indonesia: a user-centered design approach

BACKGROUND

A mobile health (mHealth) application can encourage parents and pediatric patients to be involved in caring for their child's health condition by providing the ability to identify and actively manage chemotherapy-related symptoms in their child. Several monitoring systems available today are diverse in features and system basis. This study aimed to develop and trial the Chemo Assist for Children (CAC) mHealth application for symptom management in children with acute lymphoblastic leukemia (ALL).

METHODS

In this study, the development of the CAC application went through multiple phases and methods. Study phases included: (1) development of the application's feature based on the need assessment, (2) creation of content of application based on literature review, (3) develop prototyping of CAC, (4) expert review and feedback on the application content, (5) usability testing by targeted end-user.

RESULTS

Based on need assessment, it was determined that parents with leukemia children were interested in symptom management of chemotherapy and preferred mobile applications. Therefore, a mHealth application was designed to include features to identify symptoms and provide recommendation strategies to manage the symptom. Usability evaluation by end-user revealed that mHealth is a valid, accessible, and appropriate application for users.

CONCLUSIONS

The CAC mHealth application developed can meet the needs of technology users to identify symptoms and manage chemotherapy-related symptoms in children with ALL. The CAC mHealth application can accommodate data not recorded at out-of-hospital care, increase the independence of symptom management, and improve communication between parents of children with ALL and health workers.

Treatment of breakthrough and prevention of refractory chemotherapy-induced nausea and vomiting in pediatric cancer patients: Clinical practice guideline update

This clinical practice guideline update provides recommendations for treating breakthrough chemotherapy-induced nausea and vomiting (CINV) and preventing refractory CINV in pediatric patients. Two systematic reviews of randomized controlled trials in adult and pediatric patients informed the recommendations. In patients with breakthrough CINV, escalation of antiemetic agents to those recommended for chemotherapy of the next higher level of emetogenic risk is strongly recommended. A similar recommendation to escalate therapy is made to prevent refractory CINV in patients who did not experience complete breakthrough CINV control and are receiving minimally or low emetogenic chemotherapy. A strong recommendation to use antiemetic agents that controlled breakthrough CINV for the prevention of refractory CINV is also made.

Addressing adherence to guidelines on prevention of acute chemotherapy-induced nausea and vomiting in pediatric patients

BACKGROUND

Chemotherapy-induced nausea and vomiting (CINV) is a distressing adverse effect in children receiving cancer treatment. There are evidence-based pediatric clinical practice guidelines (CPG) on chemotherapy emetogenicity and acute CINV prevention, but adherence to these guidelines is low.

PROCEDURE

A quality improvement-based study was conducted at McMaster Children's Hospital. The SMART aim was to increase adherence to guidelines on prevention of acute CINV in hospitalized patients receiving high (HEC) and moderately emetogenic chemotherapy (MEC) from baseline 25% to more than 70% by June 2021. Barriers were identified by process mapping, and a series of interventions were implemented.

RESULTS

Guideline adherence was assessed in 270 inpatient chemotherapy administrations (HEC, MEC). Data were collected on 131 charts pre interventions and 139 charts post interventions. Interventions included education, addition of guideline-recommended anti-emetics to the inpatient formulary, and implementation of a standardized CPG tool. Initial rates of total CINV guideline adherence were 25%, which improved to 72% post intervention (p < .001). In subgroup analysis, guideline adherence in the MEC group improved from 13% to 34% (p = .015), and in the HEC group from 32% to 93% (p < .001). The most common reason for nonadherence in the HEC group was failure to use aprepitant as anti-emetic, and in MEC was option for ondansetron monotherapy prophylaxis.

CONCLUSION

Using quality improvement methodology, barriers to guideline adherence were identified and interventions implemented. Guideline adherence for prevention of CINV improved, particularly in the HEC group but less for the MEC group. Future steps will include sustainability of interventions and addressing adherence in the MEC group.

Prevention of acute and delayed chemotherapy-induced nausea and vomiting in pediatric cancer patients: A clinical practice guideline

This clinical practice guideline provides recommendations for preventing acute and delayed phase chemotherapy-induced nausea and vomiting (CINV) in pediatric patients. The recommendations are based on two systematic reviews of randomized controlled trials evaluating interventions to prevent (1) acute phase CINV and (2) delayed phase CINV. Recommendations for acute phase and delayed phase CINV prophylaxis are made for patients receiving chemotherapy of varying emetogenicity, as well as for patients not able to receive dexamethasone or a neurokinin-1 receptor antagonist. Evidence gaps, including antiemetic safety and optimal dosing, were identified.

[Antineoplastic drug-induced nausea and vomiting in pediatric onco-hematology: 2022: Guidelines from the supportive care committee of the French Society of Childhood Cancer (SFCE)]

Nausea and vomiting induced by cancer treatment (CINV) remain one of the most common and feared side effects in children despite the use of new drugs to prevent them. The existing recommendations for the prophylaxis and treatment of CINV are based on adult patients in Anglo-Saxon societies. Based on a recent review of the literature, we focused on specific pediatric issues in order to offer recommendations validated by the supportive care committee of the French society for childhood cancer.

Efficacy and Safety of Olanzapine in Children Receiving Highly Emetogenic Chemotherapy: A Randomized, Double-blind Placebo-controlled Phase 3 Trial

BACKGROUND

In this trial, we evaluated the safety and efficacy of olanzapine in children receiving highly emetogenic chemotherapy.

MATERIALS AND METHODS

In this study, patients aged 3 to 18 years were randomly assigned to either the olanzapine group or the placebo group. All patients received intravenous ondansetron and dexamethasone 30 minutes before highly emetogenic chemotherapy, followed by oral ondansetron for 48 hours. Participants in the olanzapine group received olanzapine once daily on days 1 and 2, while those in the control group received a placebo in the same dosage and schedule. The primary objective was: (a) to compare the complete control rates of vomiting in the delayed phase and (b) to compare the complete control rates of vomiting in acute and overall phases. The secondary objective was to evaluate the safety of olanzapine and the need for rescue medications.

RESULTS

A total of 128 patients were randomly assigned either to the olanzapine group (n=63) or the control group (n=65). Complete control of vomiting between olanzapine and placebo group was 73% versus 48% ( P =0.005) in the delayed phase, 60% versus 54% ( P =0.46) in the acute phase, and 48% versus 34% ( P =0.117) in the overall phase, respectively. Grades 1 and 2 sedation was greater in the olanzapine group (46% vs. 14%; P <0.001). A significantly higher proportion of patients in the placebo group required rescue medications for vomiting compared with in the olanzapine group ( P =0.025).

CONCLUSIONS

Olanzapine significantly improved complete control of vomiting in the delayed phase. A considerably lesser proportion of patients in the olanzapine group needed rescue medications.

The effect of text message reminders on nausea, vomiting and quality of life in children with cancer receiving cisplatin

PURPOSE

This study was conducted to examine the effect of text message reminders on nausea, vomiting, and quality of life in children with cancer receiving cisplatin.

METHODS

The study was conducted with a pretest-posttest unpaired group model design. The study included 80 children with cancer and their parents (40 controls and 40 experiments) aged between 8 and 18 years, who were on cisplatin treatment, who did not have cognitive disability as a clinical diagnosis, who received chemotherapy during their stay in the clinic, who were literate in Turkish and who volunteered to participate in the study. The educational contents prepared by the researchers to reduce nausea and vomiting were sent to the parents in the experimental group in the form of a text message every day for three weeks. Descriptive statistics, correlation analysis, and regression analysis were used to evaluate the data.

RESULTS

While NVTS, ARINVc, ARINVp, Quality of Life Scale pretest and posttest mean scores of both 8-12 and 13-18 age control group children were similar, it was determined that the experimental group's posttest mean scores were higher than the pretest mean scores, and there was a statistically significant difference between the experimental group's pretest and posttest mean scores in terms of the group, time and group*time. In this study, the education program explains 42%, 15%, 16%, 43%, and 43% of the increase in the mean scores of NVTS, ARINVc, ARINVp, Quality of Life Scale Child and Parent Form, respectively, in children aged 8-12. Also, the education program explains 10%, 27%, 28%, 38%, and 39% of the increase in the mean scores of NVTS, ARINVc, ARINVp, Quality of Life Scale Adolescent and Parent Form, respectively, in children aged 13-18.

CONCLUSIONS

It has been observed that text message reminders effectively reduce the level of nausea and vomiting and increase the quality of life.

PRACTICE IMPLICATIONS

The results of this study, text message reminders can be applied as an alternative intervention method, and including technology-based practices in the care of children with cancer is important in increasing the quality of care.

Complementary and alternative medicine modalities used to treat adverse effects of anti-cancer treatment among children and young adults: a systematic review and meta-analysis of randomized controlled trials

Background

Dealing with the symptom burden of cancer diagnosis and treatment has led parents to seek different self-management strategies including Alternative and Complementary Medicine (CAM). The aim of this study was to perform a systematic review and meta-analysis about the use and effect of CAM modalities to treat adverse effects of conventional cancer treatment among children and young adults.

Methods

Six scientific research databases were used to identify randomized controlled trials (RCTs) from 1990 to September 2020. Included studies investigated the use of CAM to treat cancer treatment related adverse effects in children and young adults compared to controls.

Results

Twenty RCTs comprising 1,069 participants were included in this review. The included studies investigated acupuncture, mind–body therapies, supplements, and vitamins for chemotherapy-induced nausea and vomiting (CINV), oral mucositis, and anxiety among children and young adults who underwent conventional cancer treatment. Seven studies (315 participants) were included in the meta-analysis. The overall effect of CAM (including acupuncture and hypnosis only) on chemotherapy-induced nausea and/or vomiting and controls was statistically significant with a standard mean difference of -0.54, 95% CI [-0.77, -0.31] I² = 0% (p < 0.00001). There was a significant difference between acupuncture and controls (n = 5) for intensity and/or episodes of CINV with an SMD -0.59, 95% CI [-0.85, -0.33] (p < 0.00001). No significant difference was found between hypnosis and controls (n = 2) for severity or episodes of CINV with an SMD -0.41, 95% CI [-1.09, 0.27] I² = 41% (p = 0.19).

Conclusion

Current evidence from this meta-analysis of randomized controlled trials shows that CAM, including acupuncture and hypnosis only, is effective in reducing chemotherapy-induced nausea and vomiting in children and young adults. More rigorous trials and long-term effects should be investigated if acupuncture and hypnosis are to be recommended for clinical use.

Safety of Complementary and Alternative Medicine (CAM) treatment among children and young adults who suffer from adverse effects of conventional cancer treatment: A systematic review

BACKGROUND

Complementary and Alternative Medicine (CAM) is widely used around the world to treat adverse effects derived from cancer treatment among children and young adults. Parents often seek CAM to restore and maintain the child's physical and emotional condition during and after cancer treatment.

OBJECTIVES

The objectives of this review were (i) to identify literature that investigates CAM use for treating adverse effects of conventional cancer treatment, (ii) to investigate the safety of the included CAM modalities, and (iii) to evaluate the quality of included studies.

METHODS

Five scientific research databases were used to identify observational, quasi-experimental, and qualitative studies from January 1990 to May 2021. Included studies investigated the use of CAM to treat adverse effects of cancer treatment in childhood cancer.

RESULTS

Fifteen studies were included in this review. Ten quasi-experimental, 3 observational studies (longitudinal/prospective), 2 qualitative studies, and 1 study with a quasi-experimental and qualitative arm were identified. Less than half (n = 6; 40%) of the studies included reported adverse effects for the CAM modality being studied. Among the studies that reported adverse effects, they were mostly considered as direct risk, as 13% reported mainly bleeding and bruising upon acupuncture treatment, and dizziness with yoga treatment. All adverse effects were assessed as minor and transient. CAM modalities identified for treating adverse effects of cancer treatment were alternative medical systems, manipulative and body-based therapies, biologically-based therapies, and mind-body therapies. CAM modalities were used to alleviate anxiety, pain, toxicity, prevent trauma, and improve health-related quality of life, functional mobility, and physical activity levels. All studies assessed scored 70% or above according to the Joanna Briggs Institute critical appraisal for study quality checklists.

CONCLUSION

Most of the studies (58.3%) included in this review did not report adverse effects from CAM modalities used to treat adverse effects of cancer treatment in children and young adults. This lack of safety information is of concern because parents need to know whether the modality represents an extra burden or harm to the child. To improve awareness about safety in the field, a universal and uniform reporting system for adverse effects in CAM research is needed.

Improving Guideline-Congruent Care for Chemotherapy-Induced Nausea and Vomiting Prophylaxis in Pediatric Oncology Patients

PURPOSE

Chemotherapy-induced nausea and vomiting (CINV) is a very common side effect of pediatric cancer therapy. High-quality, evidence-based, pediatric-specific guidelines for prophylaxis and treatment of CINV are available. At many centers, guideline-concordant care is uncommon. We formed a multidisciplinary quality improvement team to implement guideline-concordant care for CINV prophylaxis at our center. We present the results following the first year of our interventions.

METHODS

We planned and implemented a multipronged approach in three key phases: (1) developing and publishing an acute CINV prophylaxis pathway, (2) education of providers, and (3) updating the computerized provider order entry system. We used iterative, sequential Plan-Do-Study-Act cycles and behavioral economic strategies to improve adherence to guideline-concordant CINV prophylaxis. We focused on aprepitant usage as a key area for improvement.

RESULTS

At the beginning of the study period, < 50% of patients were receiving guideline-concordant CINV prophylaxis and < 15% of eligible patients were receiving aprepitant. After 1 year, more than 60% of patients were receiving guideline-concordant care and 50% of eligible patients were receiving aprepitant.

CONCLUSION

We describe the development and implementation of a standardized pathway for prevention of acute CINV in pediatric oncology patients. With a multidisciplinary, multifaceted approach, we demonstrate significant improvements to guideline-congruent CINV prophylaxis.

Efficacy and Safety of Adding Olanzapine to the Standard Preventive Regimen for Chemotherapy-induced Nausea and Vomiting in Children: A Randomized Double-blind Controlled Trial

This study aimed to assess the additive value of olanzapine to a combination of ondansetron and dexamethasone to prevent chemotherapy-induced nausea and vomiting (CINV) in pediatric patients. A total of 40 patients between 4 to 18 years of age were enrolled in this randomized clinical trial. Both groups received a combination of ondansetron and dexamethasone, and 0.14 mg/kg olanzapine or matched placebo were administered for olanzapine and control groups, respectively. The primary end points were complete response and lack of nausea as far as three days after chemotherapy evaluated by the Common Terminology Criteria for Adverse Effects (CTCAE) v5.0 and the Multinational Association of Supportive Care in Cancer (MASCC) Anti-emesis Tool (MAT). Side effects of olanzapine were also analyzed. In patients receiving the standard regimen of ondansetron and dexamethasone, nausea was observed in 10.5% and 21% of patients according to MAT and CTCAE scales, respectively. In the olanzapine group, 37.5% (MAT scale) and 31.3% (CTCAE scale) of patients developed nausea. Complete response was observed in 84% (MAT scale) and 94.7% (CTCAE scale) of patients in the placebo group receiving ondansetron and dexamethasone. In comparison, it was observed in 87.5% (MAT scale) and 81.25% (CTCAE scale) for patients allocated to the olanzapine group. Neither acute nor delayed CINV was statistically different between placebo and olanzapine groups. The frequency of adverse effects was higher in the olanzapine group. Adding olanzapine to the standard regimen of CINV prophylaxis was only unhelpful in pediatric patients receiving moderately emetogenic chemotherapy but also associated with a higher rate of minor side effects.

A Person-Centered Approach to Symptom Assessment and Management for Children and Adolescents Receiving Cancer Treatment

OBJECTIVES

Discuss the clinical assessment and management of symptoms for children and adolescents receiving treatment for cancer with attention to a person-centered approach to care.

DATA SOURCES

Review of currently published literature and guidelines pertaining to symptom assessment and management for children and adolescents receiving treatment for cancer.

CONCLUSION

Symptoms such as pain, nausea, and fatigue are commonly reported by children and adolescents receiving cancer treatment and are associated with greater symptom burden. Symptom assessment should be tailored to the child or adolescent and include the child's or adolescent's preference for reporting symptoms and attention to the symptoms that are of greatest priority. Evidence-based guidelines for the management of symptoms, including pain and nausea, are available to guide symptom management interventions and should be tailored to provide person-centered care.

IMPLICATIONS FOR NURSING PRACTICE

Nurses can lead efforts through clinical practice and research initiatives to advance person-centered symptom care for children and adolescents with cancer on a global level. Priorities for future work to advance person-centered symptom assessment and management include (1) identification of best practices for symptom assessment, (2) attention to social determinants of health and their subsequent influence on symptom outcomes, (3) compilation of evidence for management of less commonly reported symptoms, and (4) implementation of published clinical guidelines for symptom management in practice settings.

Identifying clinical practice guidelines for symptom control in pediatric oncology

BACKGROUND

Children with cancer commonly experience distressing symptoms such as pain, fatigue and nausea. Improvements in patient outcomes have been associated with implementation of clinical practice guideline-consistent care across several domains. The objective of this study was to develop a process to identify symptom management clinical practice guidelines (CPGs) applicable to children and adolescents receiving cancer treatments.

METHODS

We focused on identifying CPGs to manage 15 symptoms. The process defined three Tiers of CPGs based upon applicability to pediatric cancer patients and ease of identification: Tier 1: endorsed by the Children's Oncology Group; Tier 2: housed in the Emergency Care Research Institute repository, or developed by the American Society of Clinical Oncology or National Institute for Health and Care Excellence; and Tier 3: identified by systematic review. We first searched for CPGs published 2015-2020 and identified Tiers 1 or 2 CPGs. If unavailable or scope was too narrow, we proceeded to Tier 3. If CPGs were not identified, we repeated these steps for CPGs published 2010-2014.

RESULTS

There were six Tier 1 and 13 Tier 2 CPGs published 2015-2020 across the 15 symptoms. Four symptoms required progression to Tier 3 because CPGs were absent (anger) or because scope was too narrow (pain, anorexia/excessive hunger and diarrhea). The systematic review identified three CPGs for pain and none for the other three symptoms. In total, CPGs were identified for 14 of 15 symptoms. None were identified for anger.

CONCLUSION

We created a process to identify supportive care CPGs for pediatric cancer symptom management and were able to identify CPGs that addressed 14 of 15 symptoms. Future work should focus on evaluating implementation techniques for these CPGs and determining the impact of these CPGs on provider and patient outcomes.

Prevention and treatment of anticipatory chemotherapy-induced nausea and vomiting in pediatric cancer patients and hematopoietic stem cell recipients: Clinical practice guideline update

This 2021 clinical practice guideline update provides recommendations for preventing anticipatory chemotherapy-induced nausea and vomiting (CINV) in pediatric patients. Recommendations are based on systematic reviews that identified (1) if a history of acute or delayed CINV is a risk factor for anticipatory CINV, and (2) interventions for anticipatory CINV prevention and treatment. A strong recommendation to optimize acute and delayed CINV control in order to prevent anticipatory CINV is made. Conditional recommendations are made for hypnosis, systematic desensitization, relaxation techniques, and lorazepam for the secondary prevention of anticipatory CINV. No recommendation for the treatment of anticipatory CINV can be made.

Chemotherapy-Induced Nausea and Vomiting: Pathogenesis, Recommendations, and New Trends

The significant physical and emotional effects of chemotherapy-induced nausea and vomiting (CINV) are experienced by cancer patients. Severe symptoms decrease the patient's quality of life and potentially deters further treatment. The five main forms of CINV (i.e., acute, delayed, anticipatory, breakthrough, and refractory) require different treatment regimens, which often include 5-HT3 receptor antagonists, NK1 receptor antagonists, and corticosteroids. Despite a significant amount of research and development of antiemetic agents, management of CINV remains a great challenge with many needs waiting to be adequately addressed, such as controlling non-acute CINV, developing appropriate CINV treatment protocols for multiple-day chemotherapy patients, and providing options for those prone to CINV despite treatment. Further research is required to optimize CINV management for these patients.

Olanzapine for Prevention of Vomiting in Children and Adolescents Receiving Highly Emetogenic Chemotherapy: Investigator-Initiated, Randomized, Open-Label Trial

PURPOSE

Chemotherapy-induced nausea and vomiting (CINV) is a significant toxicity of chemotherapy. Olanzapine is recommended in adult patients for the prevention of CINV but has not been prospectively investigated in children.

METHODS

This investigator-initiated, randomized, open-label trial evaluated olanzapine in children (ages 5-18 years) scheduled to receive the first cycle of highly emetogenic chemotherapy (HEC). All participants received aprepitant, ondansetron, and dexamethasone during and 2 days after chemotherapy. Participants in the study group additionally received oral olanzapine 0.14 mg/kg/day (rounded to the nearest 2.5 mg; maximum, 10 mg) during the chemotherapy block and 3 days postchemotherapy. The primary objective was to compare complete response (CR) rates (no vomiting and no rescue medication) between the groups in the acute, delayed, and overall periods. Nausea comparison and safety evaluation were secondary and additional objectives, respectively. The collection of outcomes and adverse events was performed daily until the completion of the overall period.

RESULTS

A total of 240 patients underwent randomization. We performed a modified intention-to-treat analysis on 231 patients (116 in the control group and 115 in the study group). A higher proportion of patients in the olanzapine group achieved CR in the acute period (78% v 59%; P = .001), delayed period (74% v 47%; P < .001) and overall period (64% v 38%; P < .001) than in the control group. The proportion of patients with no nausea was significantly higher in the olanzapine group in the acute period (74% v 52%; P < .001), delayed period (74% v 47%; P < .001), and overall period (64% v 37%; P < .001). Grade 1/2 somnolence was greater in the olanzapine group (35% v 11%; P < .001). There was no grade 3/4 somnolence reported.

CONCLUSION

Olanzapine significantly improved CR rates for vomiting in children receiving the first cycle of HEC.

Psychopharmacology in the Pediatric Oncology and Bone Marrow Transplant Units: Antipsychotic Medications Palliate Symptoms in Children with Cancer

Objectives: The present study characterized the psychiatric diagnoses and symptoms that led to the administration of antipsychotic medications in children and adolescents with cancer, and to evaluate the benefits and tolerability of these drugs in a large hospital-based pediatric hematology-oncology practice. Methods: Efficacy and adverse effects of two second-generation antipsychotics were retrospectively analyzed in 43 patients 2.9-19.6 (mean 12.1) years of age. The Clinical Global Impression-Severity (CGI-S) Scale and Improvement (CGI-I) Scale were used to evaluate psychiatric symptom severity before and following treatment, while the incidence of side effects and drug-drug interactions were collected from medical records. Results: Olanzapine was administered to 58% of patients and risperidone to 42%; the choice of drug was at the discretion of the treating psychiatrist. The common psychiatric diagnoses among these patients included adjustment disorder (37%) and medication-induced psychiatric disorders (23%). The most common psychiatric-medical symptoms included irritability/agitation (79%) and depressed mood (74%). CGI-S improved significantly (p < 0.001) between assessments, with no statistically significant difference between olanzapine- and risperidone-treated patients. CGI-I scores at reassessment indicated superiority of olanzapine as compared with risperidone. Adverse effects of treatment were mild. Conclusions: Olanzapine and risperidone can be well tolerated and ameliorate severe psychiatric-medical symptoms in children and adolescents with cancer. The potential palliative benefits of these second-generation antipsychotics (e.g., rapid onset of action, antiemesis, sedation, and appetite stimulation) increase the utility of their use in children treated in oncology and bone marrow transplant units.

Olanzapine versus metoclopramide for the treatment of breakthrough chemotherapy-induced vomiting in children: An open-label, randomized phase 3 trial

BACKGROUND

Breakthrough chemotherapy-induced vomiting (CIV) is defined as CIV occurring after adequate antiemetic prophylaxis. Olanzapine and metoclopramide are two drugs recommended for the treatment of breakthrough CIV in children, without adequate evidence. We conducted an open-label, single-center, phase 3 randomized controlled trial comparing the safety and efficacy of olanzapine and metoclopramide for treating breakthrough CIV.

PROCEDURE

Children aged 5-18 years who developed breakthrough CIV after receiving highly emetogenic chemotherapy or moderately emetogenic chemotherapy were randomly assigned to the metoclopramide or olanzapine arm. The primary objective of the study was to compare the complete response (CR) rates between patients receiving olanzapine or metoclopramide for treating breakthrough CIV during 72 hours after the administration of the study drug. Secondary objectives were to compare CR rates for nausea and toxicities between the two arms.

RESULTS

Eighty patients were analyzed (39 in the olanzapine arm and 41 in the metoclopramide arm). CR rates were significantly higher in the olanzapine arm compared with the metoclopramide arm for vomiting (72% vs 39%, P = 0.003) and nausea (59% vs 34%, P = 0.026). Seven patients in the metoclopramide arm crossed over to the olanzapine arm and none crossed over in the olanzapine arm (P < 0.001). The mean nausea score in the olanzapine arm was significantly lower than the metoclopramide arm after the initiation of the rescue antiemetic (P = 0.01). Hyperglycemia and drowsiness were more commonly seen in the olanzapine arm.

CONCLUSION

Olanzapine is superior to metoclopramide for the treatment of breakthrough CIV in children. Drowsiness and hyperglycemia need to be monitored closely in children receiving olanzapine for breakthrough CIV.

Pediatric Aggressive Mature B-Cell Lymphomas, Version 2.2020, NCCN Clinical Practice Guidelines in Oncology

Pediatric aggressive mature B-cell lymphomas are the most common types of non-Hodgkin lymphoma in children, and they include Burkitt lymphoma (BL) and diffuse large B-cell lymphoma (DLBCL). These diseases are highly aggressive but curable, the treatment is complex, and patients may have many complicated supportive care issues. The NCCN Guidelines for Pediatric Aggressive Mature B-Cell Lymphomas provide guidance regarding pathology and diagnosis, staging, initial treatment, disease reassessment, surveillance, therapy for relapsed/refractory disease, and supportive care for clinicians who treat sporadic pediatric BL and DLBCL.

Supportive care during pediatric hematopoietic stem cell transplantation: beyond infectious diseases. A report from workshops on supportive care of the Pediatric Diseases Working Party (PDWP) of the European Society for Blood and Marrow Transplantation (EBMT)

Hematopoietic stem cell transplantation (HSCT) is currently the standard of care for many malignant and nonmalignant blood diseases. As several treatment-emerging acute toxicities are expected, optimal supportive measurements critically affect HSCT outcomes. The paucity of good clinical studies in supportive practices gives rise to the establishment of heterogeneous guidelines across the different centers, which hampers direct clinical comparison in multicentric studies. Aiming to harmonize the supportive care provided during the pediatric HSCT in Europe, the Pediatric Diseases Working Party (PDWP) of the European Society for Blood and Marrow Transplantation (EBMT) promoted dedicated workshops during the years 2017 and 2018. The present paper describes the resulting consensus on the management of sinusoidal obstructive syndrome, mucositis, enteral and parenteral nutrition, iron overload, and emesis during HSCT.

Optimizing symptom control in children and adolescents with cancer

There is growing recognition of the degree to which symptoms negatively impact on children receiving cancer treatments. A recent study described that almost all inpatient pediatric oncology patients are experiencing at least one bothersome symptom and almost 60% are experiencing at least one severely bothersome symptom. Poor symptom control occurs because of challenges with communication of bothersome symptoms to clinicians, lack of clinical practice guidelines (CPGs) for most of these symptoms, and failure to administer preventative and therapeutic interventions known to be effective for symptom control. This article reviews approaches used to improve symptom control for children receiving cancer treatments. Areas addressed include systematic symptom screening and creation of CPGs for symptom management. Challenges with electronic health integration are also addressed. Several multi-symptom assessment scales have been developed but none have yet been used to directly influence patient management. The number of CPGs applicable to symptom control in pediatric oncology is increasing but remains small. Improving the creation of and adherence to CPGs for symptom management is an important priority. Finally, identifying ways that symptom management systems can be integrated into clinical work flows is essential; these will likely need to focus on electronic health records.

Latest Update on Prevention of Acute Chemotherapy-Induced Nausea and Vomiting in Pediatric Cancer Patients

PURPOSE OF REVIEW

Chemotherapy-induced nausea and vomiting (CINV) is a common cause of acute morbidity that impacts quality of life in children receiving cancer treatment. Here, we review the evolution of CINV prophylaxis guidelines in children, with an emphasis on the literature published in the last 5 years, to bring the reader up to date.

RECENT FINDINGS

Recent studies have led to the adoption of the "triple therapy" regimen of antiemetic prophylaxis (a 5-HT3 antagonist, dexamethasone, and a neurokinin-1 antagonist) as the backbone of recommendations for the prevention of CINV in children. Areas of new data include the addition of aprepitant and inclusion of palonosetron as a non-inferior 5-HT3 antagonist. In addition, there are emerging pediatric data informing patient-derived risk factors associated with CINV risk and classification of antineoplastic drugs based on emetogenicity. Several recent pediatric studies have shaped published guidelines for CINV prophylaxis in children.

Acupressure to Reduce Treatment-Related Symptoms for Children With Cancer and Recipients of Hematopoietic Stem Cell Transplant: Protocol for a Randomized Controlled Trial

BACKGROUND

We describe the study design and protocol of a pragmatic randomized controlled trial (RCT) Acupressure for Children in Treatment for a Childhood Cancer (ACT-CC).

OBJECTIVE

To describe the feasibility and effectiveness of an acupressure intervention to decrease treatment-related symptoms in children in treatment for cancer or recipients of a chemotherapy-based hematopoietic stem cell transplant (HSCT).

DESIGN

Two-armed RCTs with enrollment of 5 to 30 study days.

SETTING

Two pediatric teaching hospitals.

PATIENTS

Eighty-five children receiving cancer treatment or a chemotherapy-based HSCT each with 1 parent or caregiver.

INTERVENTION

Patients are randomized 1:1 to receive either usual care plus daily professional acupressure and caregiver delivered acupressure versus usual care alone for symptom management. Participants receive up to 20 professional treatments.

MAIN OUTCOME

A composite nausea/vomiting measure for the child.

SECONDARY OUTCOMES

Child's nausea, vomiting, pain, fatigue, depression, anxiety, and positive affect.

PARENT OUTCOMES

Depression, anxiety, posttraumatic stress symptoms, caregiver self-efficacy, and positive affect. Feasibility of delivering the semistandardized intervention will be described. Linear mixed models will be used to compare outcomes between arms in children and parents, allowing for variability in diagnosis, treatment, and age.

DISCUSSION

Trial results could help childhood cancer and HSCT treatment centers decide about the regular inclusion of trained acupressure providers to support symptom management.

Frequency, Severity, and Distress Associated With Physical and Psychosocial Symptoms at Home in Children and Adolescents With Cancer

Malignancy- and cancer-related treatments lead to multiple symptoms. Although treatments focus on cure, few research studies have examined the symptoms that accompany these aggressive and complicated treatments. The purpose of the study was to evaluate the symptoms experienced by children at home. Children (n = 25) and adolescents (n = 33) diagnosed with cancer completed the Memorial Symptoms Assessment Scale during the 5 days at home after discharge from the hospital. The most frequent physical symptoms were fatigue (52.1%), nausea (50.7%), lack of appetite (43.7%), and pain (42.3%). The most frequent psychological symptoms were difficulty sleeping (21.1%), worrying (18.3%), feeling sad (18.3%), and feeling nervous (16.9%). Significant differences were found in the overall physical and psychosocial symptoms and Global Distress Index in patients with and without pain, fatigue, and nausea. Results indicated that physical and psychosocial symptoms and Global Distress Index increased as severity of pain, nausea, and fatigue increased. Children and adolescents were experiencing many symptoms at home but were often not reporting them.

Observational Study of Pediatric Inpatient Pain, Nausea/Vomiting and Anxiety

Background: The prevalence and severity of pain, nausea/vomiting, and anxiety (PNVA) among hospitalized children is not well established. We describe the prevalence and severity of PNVA among hospitalized patients from oncology, general pediatrics, and cardiology services in a tertiary care center. Methods: Patients were recruited on admission and enrolled if their caregiver consented, spoke English, and were anticipated to stay 2-30 days. Symptoms were measured weekdays using age-validated tools. PNVA symptoms were described and compared. Results: We enrolled 496 (49.4%) patients of 1005 admitted. Patients were predominantly Caucasian (57.9%) on their first admission (53.6%). The average (SD) age was 8.6 years (5.9) in oncology, 4.2 (5.3) in general pediatrics and 2.6 (4.0) in cardiology. 325 (65.6%) patients reported anxiety, 275 (55.4%) reported nausea and 256 (52.0%) reported pain. Mean (SD) severity out of 10 was 3.7 (2.5) for anxiety, 3.2 (2.1) for nausea and 3.0 (1.5) for pain. Prevalence of PNVA was no different between clinical programs, but pain (p = 0.008) and nausea (p = 0.006) severity were. PNVA symptom co-occurrence was positively correlated (p < 0.001). Conclusions: Anxiety was the most common and severe symptom for hospitalized children. Patients in oncology demonstrated the least severe pain and nausea with no difference in anxiety between services.

Classification of the acute emetogenicity of chemotherapy in pediatric patients: A clinical practice guideline

This clinical practice guideline (CPG) provides clinicians with recommendations regarding chemotherapy emetogenicity classification in pediatric oncology patients. This information is critically important for the appropriate selection of antiemetic prophylaxis. Recommendations are based on a systematic review limited to pediatric patients and a framework for classification when antiemetic prophylaxis is provided. Findings of 87 publications informed the emetogenicity classification of 49 single-agent and 13 combination-agent regimens. Information required for the classification of many chemotherapies commonly administered to pediatric patients is lacking. In the absence of pediatric data, consultation of methodologically sound CPGs aimed at adult oncology patients may be appropriate.

Modern pediatric formulations of the soft candies in the form of a jelly: determination of metoclopramide content and dissolution

In pediatrics, it is crucial to ameliorate the unpleasant taste of oral pharmaceutical formulations in order to facilitate patient compliance. Scientists' attempt to develop modern products for children is included among the new trends in pharmaceutical technology. Designing the preparation procedures and selecting the age-appropriate dosage form should be based on a benefit-risk approach, taking into account safety, efficacy, ease of use and accessibility to the patient. Part of this process should examine the necessity for taste masking, considering organoleptic and physicochemical properties of the active pharmaceutical ingredient. This research describes the incorporation of metoclopramide hydrochloride in the form of a soft candy (jelly) containing pomegranate juice. The low cost excipients and the ease of preparation are such characteristics that qualify the proposed technique as one of the alternative methods for modern drug formulations. At the same time, metoclopramide is quantitatively determined by developing a reverse phase HPLC method. The method is accurate (%RSD = 2.63, %mean recovery = 100.75) and can be used for routine analysis. The stability of metoclopramide was satisfactory after 6 months of storage (recovery 103.43%). Dissolution of the drug exceeded 92%. The proposed formulation enclosing metoclopramide in a jelly is modern, palatable and can be administered to children.

Intravenous fosaprepitant for the prevention of chemotherapy-induced vomiting in children: A double-blind, placebo-controlled, phase III randomized trial

BACKGROUND

Fosaprepitant is a neurokinin-1 receptor antagonist, approved for the prevention of chemotherapy-induced nausea and vomiting. The data on the use of fosaprepitant in children are limited and therefore we conducted a phase III randomized controlled trial.

PROCEDURE

Children aged 1-12 years scheduled to receive moderately or highly emetogenic chemotherapy were randomly assigned to arm-A (fosaprepitant) or arm-B (placebo). Children recruited to arm-A received intravenous ondansetron plus dexamethasone followed by fosaprepitant infusion. Children recruited to arm-B received the same drugs as those given to children in arm-A, except that fosaprepitant was substituted with a placebo. Ondansetron and dexamethasone were continued for 48 hours after completion of chemotherapy. The primary end point of the study was to determine the proportion of patients who achieved a complete response (CR), defined as no vomiting, no retching, and no use of rescue medication, during the 24-120 hours (delayed phase) after administration of the last dose of chemotherapy. Secondary end points were the proportion of patients who achieved a CR during the acute phase (0-24 hours) and overall after administration of the last dose of chemotherapy.

RESULTS

One-hundred-sixty-three patients were analyzed (81 in the fosaprepitant arm and 82 in the placebo arm). CR rates were significantly higher in the fosaprepitant arm compared to those in the placebo arm during the acute phase (86% vs 60%, P < 0.001), delayed phase (79% vs 51%, P < 0.001), and overall phase (70% vs 41%, P < 0.001). Three (4%) patients in the fosaprepitant arm and sixteen (20%) in the placebo arm required rescue anti-emetics (P = 0.0017).

CONCLUSION

Addition of fosaprepitant to ondansetron and dexamethasone improved chemotherapy-induced vomiting control in children treated with moderately or highly emetogenic chemotherapy.

Identifying clinical practice guidelines for the supportive care of children with cancer: A report from the Children's Oncology Group

Providing evidence-based supportive care for children with cancer has the potential to optimize treatment outcomes and improve quality of life. The Children's Oncology Group (COG) Supportive Care Guidelines Subcommittee conducted a systematic review to identify current supportive care clinical practice guidelines (CPGs) relevant to childhood cancer or pediatric hematopoietic stem cell transplant. Only 22 papers met the 2011 Institute of Medicine criteria to be considered a CPG. The results highlight the paucity of CPGs available to pediatric oncology healthcare professionals and the pressing need to create CPGs using current methodological standards.

Safety and efficacy of nabilone for acute chemotherapy-induced vomiting prophylaxis in pediatric patients: A multicenter, retrospective review

OBJECTIVES

To describe the safety and efficacy of nabilone given to pediatric patients to prevent acute chemotherapy-induced nausea and vomiting (CINV).

METHODS

A multicenter, retrospective review of pediatric patients who received nabilone for acute CINV prophylaxis between December 1, 2010 and August 1, 2015 was undertaken. One course of nabilone was evaluated per patient. Adverse effects associated with nabilone use were noted. The proportion of patients who experienced complete acute chemotherapy-induced vomiting (CIV) control during the acute phase was determined. The acute phase was defined as starting with the first chemotherapy dose and continuing until 24 h after administration of the last chemotherapy dose of the chemotherapy block.

RESULTS

One hundred ten eligible patients (median age: 14.0 years, range: 1.1-18.0 years; 65 male) were identified. Most (109/110) received nabilone plus a 5-HT3 antagonist for CINV prophylaxis. Adverse effects associated with nabilone were experienced by 34% (37/110) of children. All were of CTCAE Version 4.03 Grade 2 or less. Sedation (20.0%), dizziness (10.0%), and euphoria (3.6%) were the most commonly reported adverse events. Nabilone was discontinued in 10 patients due to an adverse event. The proportions of patients receiving highly or moderately emetogenic chemotherapy who experienced complete acute CIV control were 50.6% (42/83) and 53.8% (14/26), respectively.

CONCLUSION

Adverse events associated with nabilone were common but of minor clinical significance. Acute CIV control in children receiving nabilone as a part of their antiemetic regimen was poor. Future work should focus on implementation of guideline-consistent CINV prophylaxis and treatment.

Emergency Department Chief Complaints Among Children With Cancer

Children with cancer have high emergency department (ED) utilization, but little is known about their chief complaints. A retrospective chart review of ED chief complaints for children with cancer (actively receiving therapy) at Riley Hospital for Children from January 2014 to December 2015 was performed. Proportions of visits and disposition for top 5 chief complaints were determined. Multivariate logistic regression analyzed factors associated with admission. There were 598 encounters by 231 children with cancer. About half (49%) had >1 complaint. The 5 most common primary chief complaints were: fever (60.2%), pain (6.5%), nausea/vomiting (5.0%), bleeding (3.9%), and abnormal laboratory values (3.3%). Admission rates varied, with the highest rates being for nausea/vomiting (66.7%). Risk factors for admission were: hospitalization in prior 4 weeks (odds ratio [OR], 2.67; confidence interval [CI], 1.77-4.02), chief complaint of fever (OR, 1.90; CI, 1.16-3.09). For each increase in number of chief complaints, odds increased by 1.45 (CI, 1.14-1.83). Black, non-Hispanic (OR, 0.44; CI, 0.22-0.88) as compared with white, non-Hispanic, younger age (OR, 0.53; CI, 0.29-0.99) or complaint of abnormal laboratory values (OR, 0.20; CI, 0.06-0.68) had lower odds of admission. Children with cancer present to the ED with multiple and varied complaints. Future interventions could aim to improve caregiver anticipatory guidance and ED visit preparedness.

Acute chemotherapy-induced nausea and vomiting in children with cancer: Still waiting for a common consensus on treatment

Chemotherapy-induced nausea and vomiting (CINV) is one of the most common treatment side-effects, and remains a significant concern, in children undergoing chemotherapy. Although adult patients receive chemotherapy regimens combined with appropriate standardized antiemetic treatment, children can receive markedly varying antiemetic treatments. A narrative review of CINV was performed regarding CINV definition, scoring system, prevention and treatment, specifically focussing on studies conducted with paediatric oncology patients. The review highlighted a lack of rigorously developed CINV scoring systems and standardized CINV pharmacological treatment for paediatric oncology patients. Different scoring systems were found to identify potential risk factors for CINV associated with the use of several different antiemetic drugs, however, few studies have been performed in children undergoing chemotherapy. Thus, CINV remains a distressing and partially controlled side-effect in the paediatric patient population. To reduce emesis and improve quality of life in paediatric oncology patients, standardized antiemetic treatment may be preferred, using a unique CINV scoring system that accounts for the emetogenic level of the chemotherapy regimen adopted and the children's clinical characteristics.

Future cancer research priorities in the USA: a Lancet Oncology Commission

We are in the midst of a technological revolution that is providing new insights into human biology and cancer. In this era of big data, we are amassing large amounts of information that is transforming how we approach cancer treatment and prevention. Enactment of the Cancer Moonshot within the 21st Century Cures Act in the USA arrived at a propitious moment in the advancement of knowledge, providing nearly US$2 billion of funding for cancer research and precision medicine. In 2016, the Blue Ribbon Panel (BRP) set out a roadmap of recommendations designed to exploit new advances in cancer diagnosis, prevention, and treatment. Those recommendations provided a high-level view of how to accelerate the conversion of new scientific discoveries into effective treatments and prevention for cancer. The US National Cancer Institute is already implementing some of those recommendations. As experts in the priority areas identified by the BRP, we bolster those recommendations to implement this important scientific roadmap. In this Commission, we examine the BRP recommendations in greater detail and expand the discussion to include additional priority areas, including surgical oncology, radiation oncology, imaging, health systems and health disparities, regulation and financing, population science, and oncopolicy. We prioritise areas of research in the USA that we believe would accelerate efforts to benefit patients with cancer. Finally, we hope the recommendations in this report will facilitate new international collaborations to further enhance global efforts in cancer control.

Management of Chemotherapy-Induced Nausea and Vomiting in Pediatric Patients

Chemotherapy-induced nausea and vomiting (CINV) is associated with a significant deterioration in quality of life and is perceived by patients as a major adverse effect of the treatment. This review summarizes the safety and efficacy of current antiemetic agents for the prevention of CINV in children. Information on antiemetic prophylaxis for CINV in children was obtained from a literature review of current peer-reviewed articles and recent international guidelines. The literature review and the international antiemetic guidelines provide recommendations for use of specific antiemetics in children based on the emetogenicity of the chemotherapy. 5-Hydroxytryptamine-3 (5-HT₃) receptor antagonists have been safe and effective in the prevention of acute emesis with a few patients experiencing mild headache. No adequate studies have been conducted to date for specific recommendations for the prevention of delayed nausea and vomiting in children. The neurokinin (NK)-₁ receptor antagonist aprepitant has been approved by the US FDA for use in children of a specific age and weight. No studies for the NK₁ receptor antagonists netupitant and rolapitant in children have been conducted. Olanzapine, an antipsychotic, has been shown to be safe and effective in preventing nausea and emesis in adult patients receiving chemotherapy. Its use in children has been limited to children with poor control of CINV; more studies are necessary in this population. In conclusion, practitioners should follow international antiemetic guidelines to provide patients with the specific antiemetics in the recommended dose for the highest possible quality of care.

The importance of evidence-based supportive care practice guidelines in childhood cancer-a plea for their development and implementation

As cure rates in pediatric oncology have improved substantially over the last decades, supportive care has become increasingly important to reduce morbidity and mortality and improve quality of life in children with cancer. Currently, large variations exist in pediatric oncology supportive care practice, which might negatively influence care. This plea underlines the importance of development and implementation of trustworthy supportive care clinical practice guidelines, which we believe is the essential next step towards better supportive care practice, and thus a higher quality of care. To facilitate international development and endorsement, the International Pediatric Oncology Guidelines in Supportive Care Network has been established.

Guideline for the classification of the acute emetogenic potential of antineoplastic medication in pediatric cancer patients

This guideline provides clinicians caring for children with an approach to assessing the acute emetogenic potential of antineoplastic therapies. It was developed by an international, inter-professional panel of clinicians and researchers using AGREE and CAN-ADAPTE methods. The emetogenicity of antineoplastic agents was evaluated and ranked as high, moderate, low, or minimal. The emetogenicity of multiple-agent and multiple-day antineoplastic therapy was also classified. Gaps in the evidence used to underpin the guideline recommendations were identified. The contribution of this guideline to the prevention of antineoplastic-induced nausea and vomiting in individual children about to receive antineoplastic therapy requires prospective evaluation.
